On-demand interference management

Abstract

Methods, systems, and devices for wireless communication are described. A base station may transmit a first signal; listen, after transmitting the first signal and during a listening interval, for a second signal from a user equipment (UE) affected by the first signal, the second signal being indicative of interference at the first UE; receive the second signal during the listening interval; and initiate an interference management procedure based on receipt of the second signal.

What is claimed is: 
     
       1. A method for wireless communication at a first user equipment (UE), comprising:
 listening, during a listening interval, for a first signal from a victim UE affected by communications to or from the first UE, the first signal indicative of interference at the victim UE; 
 receiving the first signal during the listening interval; and 
 transmitting an interference management signal to a base station serving the first UE, the interference management signal indicating that the first UE is initiating an interference management procedure based at least in part on the first UE receiving the first signal from the victim UE. 
 
     
     
       2. The method of  claim 1 , further comprising:
 receiving a registration request (RRQ) from the base station; and 
 refraining from responding to the RRQ with uplink (UL) data or a registration response (RRS) signal based at least in part on receiving the first signal. 
 
     
     
       3. The method of  claim 2 , further comprising:
 determining that a network allocation vector field is set based at least in part on receiving the first signal, wherein refraining from responding to the RRQ is based at least in part on setting the network allocation vector field. 
 
     
     
       4. The method of  claim 1 , wherein the interference management procedure is a listen-before-transmit (LBT) procedure in a direction of the base station. 
     
     
       5. The method of  claim 1 , wherein the first signal is a registration response (RRS) signal. 
     
     
       6. An apparatus for wireless communication at a first user equipment (UE), comprising:
 a processor, 
 memory in electronic communication with the processor, and 
 instructions stored in the memory and executable by the processor to cause the apparatus to:
 listen, during a listening interval, for a first signal from a victim UE affected by communications to or from the first UE, the first signal indicative of interference at the victim UE; 
 receive the first signal during the listening interval; and 
 transmit an interference management signal to a base station serving the first UE, the interference management signal indicating that the first UE is initiating an interference management procedure based at least in part on the first UE receiving the first signal from the victim UE. 
 
 
     
     
       7. The apparatus of  claim 6 , wherein the instructions are further executable by the processor to cause the apparatus to:
 receive a registration request (RRQ) from the base station; and 
 refrain from responding to the RRQ with uplink (UL) data or a registration response (RRS) signal based at least in part on receiving the first signal. 
 
     
     
       8. The apparatus of  claim 7 , wherein the instructions are further executable by the processor to cause the apparatus to:
 determine that a network allocation vector field is set based at least in part on receiving the first signal, wherein refraining from responding to the RRQ is based at least in part on setting the network allocation vector field. 
 
     
     
       9. The apparatus of  claim 6 , wherein the interference management procedure is a listen-before-transmit (LBT) procedure in a direction of the base station. 
     
     
       10. The apparatus of  claim 6 , wherein the first signal is a registration response (RRS) signal. 
     
     
       11. An apparatus for wireless communication at a first user equipment (UE), comprising:
 means for listening, during a listening interval, for a first signal from a victim UE affected by communications to or from the first UE, the first signal indicative of interference at the victim UE; 
 means for receiving the first signal during the listening interval; and 
 means for transmitting an interference management signal to a base station serving the first UE, the interference management signal indicating that the first UE is initiating an interference management procedure based at least in part on the first UE receiving the first signal from the victim UE. 
 
     
     
       12. The apparatus of  claim 11 , further comprising:
 means for receiving a registration request (RRQ) from the base station; and 
 means for refraining from responding to the RRQ with uplink (UL) data or a registration response (RRS) signal based at least in part on receiving the first signal. 
 
     
     
       13. The apparatus of  claim 12 , further comprising:
 means for determining that a network allocation vector field is set based at least in part on receiving the first signal, wherein refraining from responding to the RRQ is based at least in part on setting the network allocation vector field. 
 
     
     
       14. The apparatus of  claim 11 , wherein the interference management procedure is a listen-before-transmit (LBT) procedure in a direction of the base station. 
     
     
       15. The apparatus of  claim 11 , wherein the first signal is a registration response (RRS) signal. 
     
     
       16. A non-transitory computer-readable medium storing code for wireless communication at a first user equipment (UE), the code comprising instructions executable by a processor to:
 listen, during a listening interval, for a first signal from a victim UE affected by communications to or from the first UE, the first signal indicative of interference at the victim UE; 
 receive the first signal during the listening interval; and 
 transmit an interference management signal to a base station serving the first UE, the interference management signal indicating that the first UE is initiating an interference management procedure based at least in part on the first UE receiving the first signal from the victim UE. 
 
     
     
       17. The non-transitory computer-readable medium of  claim 16 , wherein the instructions are further executable by the processor to:
 receive a registration request (RRQ) from the base station; and 
 refrain from responding to the RRQ with uplink (UL) data or a registration response (RRS) signal based at least in part on receiving the first signal. 
 
     
     
       18. The non-transitory computer-readable medium of  claim 17 , wherein the instructions are further executable by the processor to:
 determine that a network allocation vector field is set based at least in part on receiving the first signal, wherein refraining from responding to the RRQ is based at least in part on setting the network allocation vector field. 
 
     
     
       19. The non-transitory computer-readable medium of  claim 16 , wherein the interference management procedure is a listen-before-transmit (LBT) procedure in a direction of the base station.
